Split-Entry House Plans: Split-entry house plans, also known as split-level house plans, rose to popularity during the 1950s as a multi-story modification of the then dominant one-story ranch house plans. Split-level house plans retain the horizontal lines, low-pitched roofs and overhanging eaves of ranch house plans, but add a two-story unit divided at mid-height to a one-story wing to create three floor levels of interior space. Three levels make it possible to locate and accommodate three types of living spaces—quiet living spaces, noisy living and service spaces, and sleeping spaces—all on three separate levels. Our collection of split-entry house plans offers a variety of styles and sizes to suit your family.
